Thanks for the input. The thing is, I don't check my account regularly (the last time was like 10 days ago), so I really have no idea when it changed. It could have been 9 days ago; it could have been half an hour ago. No way of knowing, other than to just wait, I guess.
Is there any way (other than to order GCMS notes) to know whether, at this point, the application is likely to be refused? I don't expect it to be, but reading on here and seeing so many worst-case scenarios can make you a bit anxious!
